WARP-LINKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 288,032, dated November 6, 1883,

Application filed February 6, 1833, (No model and exact description.

My improvements, relate to machines for linking warps as they are delivered from warping-machines; and the invention consists in certain novel features constructed and combined, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents in side elevation the de livery portion of a warping-machine with the linking mechanism. Fig. 2 is an end View of the linking mechanism. Fig. 3 is a longitudinal section of the guide-pin connection of the hook. Figs. 4, 5, 6, and 7 are cross-sections of the hook on the respective dotted lines abcd.

A is the standard of the warping-machine,

carrying the pivoted delivery horn or tube 13,

which is to be moved froin side to side in the usual manner.

O is a fork fixed beneath the delivery end of tube B for receiving the loops of the warp.

D is a slide fitted for horizontal reciprocation in side guides, one of which is shown at E, and connected by a rod, F, to a crankwheel, G, that is to be rotated, by suitable con nections, with a prime mover, so asto recipro- Gate the slide D.

H is the looper jointed at I to the slide D, with its forward hook-shaped end, 6, extendingbetweenthe arms of the fork O, and having its rear end beveled, and formed with a groove, K. as shown in Figs. 6 and 7 L is a pin placed in position for engaging the groove K in the forward movement of the looper H. As shown in Fig. 3, the pin L is carried by a socket, M, containing around the pin a spiral spring, N, that projects the pin.

0 is a roller in fixed bearings, and O a second roller hung on a lever, P, and drawn toward roller 0 by a spring, P. The upper end of lever P is positioned to bear on the crankwheel G, so that the rollers are separated, ex-

cept at one point,in the movement of the mechanism, when a notch in the wheel allows the roller 0 to move to the roller 0.

The arms of the fork O are bent upward at their forward ends, 0, so as to support the loop made by the tube B below the end of the looping-hook e, and the rear portion of the arms of the fork O is inclined upward at 0, so as to raise the loop upward as it is drawn backward by the looper, as hereinafter described. Beneath its hook the looper is formed with a proj ection for carrying the looped warp. The external ends of arms of the fork G are bent inward, and, as shown in Fig. 4, the forward portion of looper H is grooved at f to pass upon and cover the ends of the arms of the fork O, as represented in Fig. 2, so as to prevent entanglement of the warps with the said ends.

fork G, and it drops down over the loop in the angle of the arms, thus forming a link. The further movement of the looper in the same direction clears it from pinL and the hook end 6 drops, so that at the backward movement the loop on fork G is engaged and carried back and upward. Tube B now swinging to the other side, another loop is laid on fork O, andthe operation is repeated. At the backward movement of looper H,'its hook end 6, gradually ascending the incline 0, causes its rear end to descend and the pin L is pressed back into its socket by the inclined surface h of the looper, and when the looper attains its original level the pin L springs into slot K, as before. Gravity causes the rear end of loop to descend as soon as released from hook until the two rollers grasp and pull it. The linked warps pass down between rollers 0 0, one of which is rotated by means of a belt, 0, driven by a pulley on shaft, J, continuously, and at the moment looper H is in its backward posi- IOO ment with'the'effect of giving a pull, so that the links are tightened and kept of uniform length.

The method of attaching this linking device to a warping-machine is common, as shown in Patent No. 25,501, and the device there shown for oscillating tube B would answer the same purpose in my invention; but as this vibratory 1I1OV61116I1U1S intermittent and bears a fixed re lation to the reciprocating movement of looper H, I will describe one means for accomplishing the same. Let the pipe B be pivoted at B to the frame A. Let its arm B engage a cam on shaft J. This cam is shaped to hold the pipe still for nearly one-half a revolution, and then to suddenly swing it one way across fork -O. The arm now holds the pipe still for nearly another half revolution and then suddenly swings it back. Upon the same shaft with wheel G may be a toothed wheel of the same size engaging an intermediate wheel, Q, which communicates motion from wheel R. The gear-wheelon the shaft of wheel G is one-half the size of wheel R. The latter is continuously revolved by the driving-power. Each revo- G, giving a forward thrust and a withdrawal of looper H; then pipe B swings the other way across, and another revolution of wheel G produces a similar result. This construction producesvery rapid linking of the warp.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The, fork 0, having arms inclined attheir rearends, substantially as and for the purpose specified,

2. The combination, with the fork C, the slide 1), means for reciprocating it, and the looper H, provided with the slot K, and beveled edge h, pivoted to said slide, of the pin L and spring N as shown and described.

3. The looper H, formed with grooves f, and

provided with means for operating it, in combination with a fork having ends bent inward, substantially as described, for' the purpose specified.
